The COM.AIR monitor offers the highest level of reliability and accuracy available in compressed air systems dewpoint measurement. It is highly regarded by manufacturing engineers for its robust packaging, accuracy, long life, fast response and ease of use. The COM.AIR employs a chilled mirror sensor, the most accurate commercial dew/frost point sensor type available, to deliver continuous, drift-free dewpoint measurement in compressed air systems without the need for regular calibration or sensor replacement. The COM.AIR is a complete dew/frost point monitoring system contained in a NEMA-12 enclosure for use in industrial environments. The wall-mountable package contains the sensor, control circuitry and flow control assembly. An alarm relay, horn and visual indication plus an analog output are included.
